The study of venous ductus, a vessel that arises in the portal sinus and carries richly oxygenated blood from the placenta to the left ventricle through the foramen ovale, allows the understanding of fetal hemodynamics and closes after the beginning of postnatal life. With a typical three-phase wave, always antegrade in physiological conditions, ca...

The extent of the Nuchal Translucency (NT) is a widely accepted method in screening for chromosomal abnormalities. His technique is well described and standardized, referring as increased when the measure is above the 95th percentile. Its combination with maternal age, nasal bone and biochemical markers, can detect approximately 90% of fetuses with...

Selective intrauterine growth restriction occurs in 10-19% of monochorionic twins, and is associated with increased mortality important and perinatal morbidity. The clinical course is given largely by the presence of placental vascular anastomosis and asymmetric distribution. It classified into three types according to the proposed Doppler umbilica...

Identification of fetal chromosomal abnormalities is one of the main issues which need to be addressed by any obstetrician involved in diagnosis of congenital anomalies. Clinical and cytogenetic characteristics were analyzed in pregnant women subjected to amniocentesis. This was an observational descriptive retrospective study that included consecu...

This case report illustrates the prenatal diagnosis of fetal hypothyroidism in a nulliparous 31-year-old woman with a history of four previous cesarean sections. She was presented with chronic renal failure of unknown etiology and had been on dialysis for 3 years along with a subclinical hypothyroidism. At 21.4 weeks of gestation, color Doppler rev...

Neural tube defects (NTDs) include a wide spectrum of congenital malformations. The most common is the open spina bifida that occurs with varying degrees of paralysis of the lower extremities and bladder and bowel disorders. Currently it is possible to reduce NTDs by folic acid (FA). The main objective or this study was to determine periconceptiona...

The agnathia-holoprosencephaly complex or disgnatia complex constitutes a group of severe malformations that compromises the development of the central nervous system and the branchial archs its low frequency, 1:100,000 neonates. This is the first case report in the Paraguayan literature, pregnant girl of 16 years old, no exposure to teratogens, re...

Illicit drug use and dependence is a serious social problem with high maternal and fetal morbidity. Supply increase and propitious social context allowed that the diffusion of the use of illicit toxic substances entails a growing incidence in pregnant women who use illicit drugs and an increase of newborns affected by the practices of their mothers...

The pulmonary sequestration (SP) is rare and characterized by the presence of pulmonary tissue not joined to the rest of the normal lung. It could be intralobar or more commonly extralobar. The definite diagnosis of a fetal upper abdominal mass can be made only after birth and following a series of ultrasonographic or image exams. We present the cl...

Doppler evaluation of the flow in the ductus venosus in the first trimester of pregnancy has contributed with clinical information relevant for parents counselling. Not only was effective in tracking chromosomal abnormalities such as trisomy 21, decreasing the rate of invasive procedures, but also in tracking congenital heart disease, redefining th...

The cervical cancer is the most common among women in our country and the most effective way to early detect it is the PAP. The objective of this work was to identify knowledge, attitudes and practices on the PAP smear test in women attending Public Hospitals of the Department of Alto Paraná. It is a descriptive study which applied structured quest...

The detailed sonographic evaluation of the fetal anatomy enables the detection of malformations as well as ultrasound markers of chromosomal defects, specially analyzing the nuchal translucency, which represents the thickness of the sonolucent area located between the skin and the subcutaneous interface of the embryo at cervical level, observed bet...

Myotonic Dystrophy adult form (MDA) is a rare neuroendocrine degenerative disease of genetic origin with autosomal dominant inheritance. Its main characteristics are myotonic dystrophy and muscular weakness. MDA is infrequently associated with pregnancy, since patients often have hypogonadism. Pregnancy is often aggravated with the presence of hydr...
